Description

Constructs a geodesic circle centered on the specified point. The esriCurveDensifyByAngle and esriCurveDensifyByDeviation densification methods are supported. If this method is applied to a polygon, the output polygon will have one or two parts, depending on the size of the ellipse. If the ellipse covers both poles and covers a hemisphere, the ellipse perimeter becomes the inner ring (the hole) and the horizon rectangle for the GCS becomes the outer ring.
